The preparation of biodiesel using microwave has received wide attention recently, and is summarized in terms of heterogeneous acid and basic catalysis transesterification. The heterogeneous catalyst process of biodiesel promoted by microwave has the advantages of rapid reaction, energy saving and environmental amity, and the resulting product is easy to separate from byproduct. Solid acid and base were selected as catalysts in the research. The transesterification reaction was finished in 10~30 min when promoted by microwave, and the conversion of transesterification reaction was comparable to or higher than that by traditional heating method. These catalysts can be reused several times.
